The hostcache up to now as been updated in the discard callback
but without checking if we are all done (the race where there are
more than one calls and the counter has not yet reached zero). This
means that when the race occurs, we end up calling the hc_upate
more than once. Also alternate stacks can keep there srtt/rttvar
in different formats (example rack keeps its values in microseconds).
Since we call the hc_update *before* the stack fini() then the
values will be in the wrong format.

Rack on the other hand, needs to convert items pulled from the
hostcache into its internal format else it may end up with
very much incorrect values from the hostcache. In the process
lets commonize the update mechanism for srtt/rttvar since we
now have more than one place that needs to call it.

Distinguish between truly invalid requests and those that fail because
we've already joined the group. Both cases fail, but differentiating
them allows userspace to make more informed decisions about what the
error means.

For example. radvd tries to join the all-routers group on every SIGHUP.
This fails, because it's already joined it, but this failure should be
ignored (rather than treated as a sign that the interface's multicast is
broken).

This puts us in line with OpenBSD, NetBSD and Linux.

On rk3399 the VOP-little node has a single 'port' property (not a

There is a NFSv4 file attribute called TimeCreate
that can be used for va_birthtime.
r362175 added some support for use of TimeCreate.
This patch completes support of va_birthtime by adding
support for setting this attribute to the server.
It also eanbles the client to
acquire and set the attribute for a NFSv4
server that supports the attribute.

platforms that for whatever reason cannot include the RATELIMIT option
can still work with rack. It adds two dummy functions that rack will
call and find out that the highest hw supported b/w is 0 (which
kinda makes sense and rack is already prepared to handle).

IF non-existend gateway was specified, the code responsible for calculating
 an updated nexthop group, returned the same already-used nexthop group.
After the route table update, the operation result contained the same
 old & new nexthop groups. Thus, the code responsible for decomposing
 the notification to the list of simple nexthop-level notifications,
 was not able to find any differences. As a result, it hasn't updated any
  of the "simple" notification fields, resulting in empty rtentry pointer.
This empty pointer was the direct reason of a panic.

Fix the problem by returning ESRCH when the new nexthop group is the same
 as the old one after applying gateway filter.
